Abstract: A reconfigurable optical channel monitor selects and determines a parameter of desired optical channel(s) from and/or to an optical WDM input signal. The OCM includes a spatial light modulator having a micro-mirror device with a two-dimensional array of micro-mirrors that tilt between first and second positions in response to a control signal from a controller in accordance with a switching algorithm and an input command. A collimator, diffraction grating, and Fourier lens collectively converge the optical input channels onto the micro-mirrors array. The optical channel is focused onto a plurality of micro-mirrors. To select each input channel, a group of micro-mirrors associated with each desired input channel is tilted to reflect the desired input channel back along the return path to a photodetector and processing unit to determine a parameter of the selected input signal.

Abstract: A reconfigurable multifunctional optical device has an optical arrangement for receiving an optical signal, each having optical bands or channels, and a spatial light modulator for reflecting the at least one optical signal provided thereon. The optical arrangement features a free optics configuration with a light dispersion element for spreading each optical signal into one or more respective optical bands or channels for performing separate optical functions on each optical signal. The spatial light modulator includes a micro-mirror device with an array of micro-mirrors, and the respective optical bands or channels reflect off respective micro-mirrors. The free optics configuration includes a common set of optical components for performing each separate optical function on each optical signal. The separate optical functions reflect off separate non-overlapping areas on the spatial light modulator. The separate optical functions include optical switching, conditioning or monitoring functions.

Abstract: An optical spectrum analyzer (OSA) (10) sequentially or selectively samples (or filters) a spectral band(s) (11) of light from a broadband optical input signal (12) and measures predetermined optical parameters of the optical signal (e.g., spectral profile) of the input light (12). The OSA (10) is a free-space optical device that includes a collimator assembly (15), a diffraction grating (20) and a mirror (22). A launch pigtail emits into free space the input signal through the collimator assembly (15) and onto the diffraction grating (20), which separates or spreads spatially the collimated input light, and reflects the dispersed light onto the mirror (22). A N4 plate (26) is disposed between the mirror 22 and the diffraction grating (20). The mirror reflects the separated light back through the N4 plate (26) to the diffraction grating (20), which reflects the light back through the collimating lens (18). The lens (18) focuses spectral bands of light (η 1- η N ) at different focal points in space. One of the spectral bands (11) is focused onto a receive pigtail (28), which then propagates to a photodetector (30). A pivoting mechanism (34) pivots the diffraction grating 20 or mirror (22) about a pivot point (36) to sequentially or selectively focus each spectral band (11) to the receive pigtail (28). A position sensor (42) detects the displacement of the diffraction grating (24) or mirror.

Abstract: A reconfigurable optical add/drop multiplexer (ROADM) selectively drops and/or adds desired optical channel(s) from and/or to an optical WDM input signal. The ROADM includes a spatial light modulator having a micro-mirror device with an array of micro-mirrors, and a light dispersion element. The micro-mirrors tilt between two positions in response to a control signal provided by a controller in accordance with a switching algorithm and input command. Collimators, diffraction gratings and Fourier lens collectively collimate, separate and focus the optical input channels and optical add channels onto the array of micro-mirrors. Each optical channel is focused on micro-mirrors of the micro-mirror device, which effectively pixelates the optical channels. To drop and/or add an optical channel to the optical input signal, mirrors associated with each desired optical channel are tilted away from a return path to the second position.
